Title: Método e equipamento para efetuar determinação de taxa usando códigos de cobertura walsh ortogonais dependentes da taxa
Inventor: BLACK PETER J
IPC: H04B1/707
Filed: 1999-02-03
Abstract: Patente de Invençã: MéTODO E EQUIPAMENTO PARA EFETUAR DETERMINAçãO DE TAXA USANDO CóDIGOS DE COBERTURA WALSH ORTOGONAIS DEPENDENTES DA TAXA. Um método e equipamento para determinação de taxa em um sistema de comunicação usando códigos de cobertura Walsh ortogonais dependentes da taxa. Os códigos Walsh ortogonais dependentes da taxa são usados para cobrir símbolos de código repetidos antes da transmissão através de um link de comunicação. Os códigos Walsh compreendem códigos binários ortogonais que aumentam em potências de dois para cada taxa de dados no sistema. Os símbolos de código são repetidos e a seguir cobertos na taxa de símbolo  usando-se os engenhosos códigos Walsh ortogonais. Os blocos de taxa de erros de símbolo (SER) são usados para gerar medidas SER dependentes da taxa para cada uma das taxas candidatas. Estimadores SER (230, 232, 234, 236) associados com combinadores soft (204, 206, 208, 210) usando hipóteses de taxa de dados incorretas produzem elevadas taxas de erro de símbolos com relação à taxa de erro de símbolos produzida pelo estimador SER (230, 232, 234, 236) associado com o combinador soft (204, 206, 208, 210) que está usando a hipótese de taxa correta. Em outra modalidade calculadores de medidas de energia (250, 252, 254, 256) substituem os estimadores SER (230, 232, 234, 236) e são usados para gerar medidas de energia recodificas dependentes da taxa para cada taxa de dados candidata. As medidas de energia produzem uma estimativa da energia de símbolos e a energia de símbolos é usada como um indicador da taxa de dados.

Patent BR-9908353-A (BR)
Inventor: FREEL BARRY
IPC: C08H8/00
Filed: 1999-01-29
Abstract: This invention is directed to a method of preparing a natural resin by liquefying wood, bark, forest residues, wood industry residues, or other biomass using fast pyrolysis in order to produce product vapours and char. Following removal of the char from the product vapours, a first set of compounds are removed from the product vapours by rapid quenching in order to obtain a remaining selected product vapour from which a natural resin is obtained. The natural resin comprises a total phenolic content from about 30 % to about 80 % (w/w), and is further characterized as having a pleasant smoky odour. The natural resin has surprisingly been found to be suitable for use within adhesive formulations without requiring any further extraction or fractionation procedures. Adhesives comprising up to 60 % natural resin have been prepared and tested in board production and found to exhibit similar properties associated with commercially available resins. The natural resin may substitute for phenol, or for both phenol and formaldehyde within phenol-containing resins. Similarly, the natural resin can replace a substantial part of the components within urea-containing resins.

Title: Limiting orifice drying of cellulosic fibrous structures apparatus therefor and cellulosic fibrous structures produced thereby
Inventor: ENSIGN DONALD E
IPC: B32B7/00
Filed: 1993-06-28
Granted: 1997-03-27
Abstract: A method and apparatus for drying of a cellulosic fibrous structure having constant basis weight and/or density or multiple regions varying in basis weight and/or density. Such a cellulosic fibrous structure may have a nonuniform moisture distribution prior to drying by the disclosed method and apparatus. An equally or more uniform moisture distribution is achieved by providing a micropore medium in the air flow path which has a greater flow resistance than the interstices between the fibers in the cellulosic fibrous structure web. The micropore medium is the limiting orifice in the air flow used in the drying process. The micropore medium may be executed in a laminate of plural laminae, each of successively increasing or decreasing pore size. This arrangement provides the advantage that minimal sagging or deformation of each lamina into the next coarser lamina occurs and lateral air flow between the micropore medium and the cellulosic fibrous structure is reduced. The micropore medium may be disposed either upstream or downstream in the air flow path of the cellulosic fibrous structure to be through-air dried.

Title: Ecstasy-class analogs and use of same in detection of ecstacy-class compounds
Inventor: ROUHANI RIAZ
IPC: A61K47/48
Filed: 2001-03-06
Abstract: The present invention provides a system for the improved detection of ecstasy-class compounds in biological samples. New ecstasy-class analogs are provided for detection of such ecstasy-class drugs. These analogs are compounds, or salts thereof, of a 2-amino-methylenedioxyphenyl (MDP) derivative attached to Z, where Z is a moiety capable of bonding, either directly or indirectly, with an immunogenic carrier, a detectable label, or a solid capture vehicle. Such analogs may be used to construct immunogens, enzyme or enzyme-donor conjugates, and other conjugates. The immunogens reproducibly generate antibodies with an exquisite ability to distinguish various ecstasy-class drugs in biological samples from potentially interfering substances. The specific antibodies and the conjugates may be used to distinguish and measure various ecstasy-class compounds in biological samples, such as those obtained from an individual suspected of substance abuse. In another aspect, the invention includes certain reagents, reagent combinations, and kits for performing assay methods for ecstasy-class compounds in a biological sample.

Title: Screen printing apparatus
Inventor: YAMASAKI KIMIYUKI
IPC: B41F15/26
Filed: 2001-07-17
Abstract: A screen printing apparatus prints cream solder through a pattern hole of a mask plate, to which a substrate is brought into contact, by sliding a squeegee head. The mask plate, to which the substrate is positioned, is three-dimensionally measured from its above, thereby detecting a positioned status. Based on the detection result, the positioned status is corrected by driving a substrate-positioning-section. As a result, the substrate is always exactly positioned to the mask plate, and quality print is thus maintainable.
